1337 CE
A year defined by the outbreak of the Hundred Years' War between England and France, a dynastic and territorial conflict that would reshape both kingdoms and dominate European affairs for over a century.
Geopolitics & Diplomacy
- King Philip VI of France declared the confiscation of the English-held Duchy of Aquitaine in May, provoking King Edward III of England to assert his own claim to the French throne.
- Edward III of England formally claimed the French crown through his mother Isabella, daughter of King Philip IV of France, challenging the Valois succession and providing a legal pretext for war.
- The outbreak of the Hundred Years' War drew in allies on both sides, with England securing alliances with Flanders, the Holy Roman Empire, and other continental powers against France.
Conflict & Security
- Initial military operations in the Hundred Years' War consisted of raids, naval skirmishes, and diplomatic maneuvering rather than large-scale pitched battles.
- The wool trade between England and Flanders became a strategic weapon, as Edward III used embargoes on English wool exports to pressure Flemish cities into supporting him against France.
Economy & Finance
- Edward III's war preparations placed enormous financial demands on the English crown, requiring parliamentary taxation and loans from Italian banking houses.
- The Flemish textile industry, dependent on English wool imports, was drawn into the conflict as Flemish cities allied with England to secure their vital raw material supply.
Climate & Environment
- Atmospheric carbon dioxide concentration was approximately 272 parts per million, as later confirmed by ice core analysis.
Culture & Society
- The estimated world population was approximately 380 million.
